HARROW.

SPECIFICATION forming part of Letters Patent No. 468,081, dated February2, 1892.

Application filed \Tl1118 13, 1891. Serial No. 396,160. (No model.)

To all whom it may concern.-

Be it known that I, AMOS O. \VICKHAM, a citizen of the United States,residing at Carthage, in the county of Jasper and State of Missouri,have invented a new and useful l-Iarrow, of which the following is aspecification.

This invention relates to improvements in harrows; and the objects inView are to provide a cheap and simple construction of harrow adaptedfor cultivating cotton, corn, or other growing plants, whether plantedupon ridges or in furrows, and adapted to use either ordinarybarrow-teeth or the bull-tongue species.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be particularly pointed out in theclaim.

Referring to the drawings, Figure 1 is a perspective of a harrowconstructed in accordance with my invention, the same being connected toa cultivator. Fig. 2 is an enlarged detail in perspective of a portionof the harrow-bar. Fig. 3 is a rear elevation of the harrow-bar. Fig. 4is a vertical section through connection between harrow-bar andstandard. Fig. 5 is a detail of the washer for securing the teeth.

Like numerals of reference indicate like parts in all the figures of thedrawings.

1 designates a harrow-bar, which may be constructed of wood or of lightangle-iron, as desired, and in the present instance of the latter. Thebar is duplicated, and each is provided with a series of verticalperforations 2. These vertical perforations may receive ordinaryharrow-teeth, as will be obvious, or, as shown in the present instance,receive vertical bolts 3. The bolts 3 are provided at their lower endswith the ordinary heads and between said heads and the lower edge of thebarrow-bar with washers 4, which washers are U-shaped in crosssection,having opposite vertical flanges 5. These flanges are notched, as at 6,and are adapted to be drawn up into engagement with the lower edge ofthe barrow-bar through the medium of nuts 7, mounted in the upper endsof the bolts, above the barrow-bars.

S designates a series of bull-tongue harrowteeth the shanks of which areabruptly rearwardly bent, and each rests in a Washer between the flangesand has passed therethrough the bolt for connecting the washer. It willbe obvious that by changing the notches that engage the lower edge ofthe barrow-bar the disposition of the teeth with relation to theharrow-bar may be altered.

Each barrow-bar is provided with a perforation 10 at each side of itscenter, and in each perforation is mounted a hook-shaped bolt 11,provided upon its front end with a binding tap or nut 12. Thesehook-shaped bolts receive the rearwardly and downwardly bent terminals13 of a pair of V-shaped dragbars or standards 15, which are coupled byclevises 16 to the frame 17 of an ordinary cultivator. One standard orterminal of each drag-bar is shorter than the other, so that the longerterminal of each drag-barbeing located in the outer hook saidharrow-bars are diverged toward their outer ends, and thus travel in aninclined manner to the line of draft or obliquely, as will be apparent.By adjusting the outer hook lower upon the outer terminal of thedrag-bar each barrow-bar will decline toward its outer end, and thuswill be adapted for hilling up. By raising the outer end of theharrow-bars they will be adapted for cultivating listed corn orharrowing the sides of furrows or hills. It will be obvious that thedrag-bars may change positions, so that the outer ends of theharrow-bars will converge to the front, and in this manner adapted tohart-ow the opposite sides of a cot ton-hill and clear the same oftrash.

Various other manners may be easily devised for using a harrowattachment thus constructed to advantage in the cultivation of variouskinds of crops, and especially adapted for the cultivation of cotton andlisted corn, both of which, and especially the former, are wellrecognized as being difficult to cultivate with any degree of success.

Having described my invention, what I claim is- In an attachment of theclass described, the combination, with opposite barrow-bars, eachprovided with a series of perforations, of bolts mounted in theperforations and terminating at their lower ends in heads, U-shapedWash- In testimony that I claim the foregoing as ers mounted on the'bolts' and having their my own I have hereto afiixed my signature in IOopposite flanges notched to engage the lower presence of two Witnesses.
